Discussion:
Class template basic_iostream has no typedefs. The typedefs itinherits from its base classes can't be used, since (for example)basic_iostream<T>::traits_type is ambiguous.
Proposed resolution:
Add the following to basic_iostream's class synopsis in 31.7.5.7[iostreamclass], immediately afterpublic:
// types: typedef charT char_type; typedef typename traits::int_type int_type; typedef typename traits::pos_type pos_type; typedef typename traits::off_type off_type; typedef traits traits_type;
